I just purchased some fresh hops (freshops) at my LHBS -- do I use them in the same weight as pellets when a weight for hops is provided in a recipe (assuming the AA are the same)? I tried to search for this and didn't come up with anything, appreciate any help.

Found an IBU calculator. Link goes to a site with places to input hop variety, alpha acid percentage, boil time, fresh or plug hops vs. pellet, wort gravity, wort volume, etc. Nice tool for playing around if you don't have a brewing software (I do not).
Anyway, here's the link: http://www.rooftopbrew.net/ibu.php
